ABSTRACT:
An electromagnetically controlled spring clutch mechanism for selectively connecting drivingly a first rotating element and a second rotating element. The spring clutch mechanism comprises a rotating shaft, a rotor adapted to be rotated as a unit with the rotating shaft, an armature assembly including an armature member, a supporting member and a biasing spring member disposed between the armature member and the supporting member, an electromagnetic device for magnetically attracting the armature member to the rotor, a first boss member adapted to rotate as a unit with the rotating shaft, a second boss member adapted to rotate as a unit with the second rotating element, and a coil spring wound in a predetermined direction and received about, and spanning, the first and second boss members. Also provided is a composite magnetically controlled spring clutch assembly for selectively connecting drivingly an input rotating element rotated in a predetermined direction to an output rotating element to rotate the output rotating element selectively in the predetermined direction or in a direction opposite to the predetermined direction, which is composed of two electromagnetically controlled spring clutch mechanisms of the first-mentioned type.
